.Patented Apr. 21 1914.

To all 'whom 'it may concern,

Be it known that la, MAX (ioniinnu, a cilil zen or the Swiss Republic. residing at Vancouver, in the Province ot iiritish Columbia, Canada, have invented certain new und useful lrnproveinents in lvlilking Devices, ol which the following is a specification'.

This invention relates to a cow milking machine of that class wherein the milk is withdrawn from the tout without suction and without any mechanieolaction being` applied to the udder.

The improvements are directed to the Ineens by which the hollow silver needle through which the milk is withdrawn is supported in the tent of the animal without any necessity for much handling and also in the provision whereby air is prevented from entering the teat so that the outflow of the milk 'is uninterrupted.

The invention is particularly described in the following specification, reference being mede to the drawings by which it is accompanied, in which:

Figure l shows the apparatus complete with one teat attachment, the air sealing milk collecting vessel being in section. Fig. 2 is a plan ofthe teat attachment. Fig. 3, a plan ot theleollecting vessel. Fig. 4:, an enlarged detail of the teat needle, and Fig. 5 is e cross section of the saine on the lines 5 5 on Fig. 4. y

ln these drawings 2 represents in dot and dash lines the lower part of the udder and the toet of a cow; 3 is a tube which is connected to each individual teat, in the upper end of which tube is removably socketed a hollow silver needle l Vhaving a series of elongated slits '5 near the upper end, as shown in Fig'. 4;'.

Extendin across the upper end of the tube 3 at t e lace of attachment of the needle d is a fnrum bar 6, on each -end of which at 8 is pivotally mounted e clump lever 7. The end of euch lever 7 projects about halfway up the needle l and .has a crescent shaped end 9 to bear against and secure e hold of the teat in which the needle is inserted. Below the tulcrum 8 these levers 7 are produced to form linger engagements l@ by pressing which together relenses the crescent ends 9 from engagement with the teat. These teat holding levers 7 ere normally pressed into engagement with the teat in the duct ot which the needle 4 is inserted, by a spring 11 coiled on the lower end ol' the tubefi and acting bet-Ween a nut 1G threaded on the tube 3 and the underside ole :i sleeve l2 slidable on the tube,

which sleeve is pin-connected on euch side :1t 13 to :i link '1.4L which is also ypin-conneclod ot l5 to the lever 7 intermediate of the fulcruin 8 and the linger engagemei'it 10. By this means the action of the spring -l'l forces up thesleeve 'l2 and pushes outward the lower ends ot' the lever 7 to 'press inward the crescent. shaped ends of these levers to grip the tout, :and this grip may be relieved by pressing' the finger engaging ends l() of these levers together. l The strength .of the spring may be adjusted by the nut 1:6 to give the required holding grip.

0n the tube belowl the nut 16 isy attached a flexible tube 1 7 by which each teat attachment is connected to a tube i8 in the cover 19 ot u collecting vessel 20. lhese tubes i8 project below the cover lt) to approximately the bottom oil the vessel 2O and the delivery pipe 21. from the vessel projects upward within the vessel to above the lower ends of the tubes 18 so that when the milk begins to flow over 2l a liquid seal prevents air passing up to the tent.

The cover lil is removably attached to the vessel by any convenient means. lt is here shown as secured by an L shaped slot 22 on each side oi' the cover engaging a pin 23 projecting from each side or' the vessel. The tube 2l delivers into the milk pail by means of a'flexiblo tube 24 in which a` glass lsight tube Q5 is inserted through which the flow of milk may bevobserred.

In use, the crescent clamp members being drawn apart by pressing together the ends flO of the levers? between the lingers. the teat needle 4 is inserted in the duct of 4the teat of the animal up to the iulcrum bar 6. When the clamp levers are released lthe needle is supported and retained in the teat by the resilient grip of the crescent ends 9 on the lower part of it` As the milk flows through the hollow needle 'Il and .intothe vessel 20 it rises over the lower ends of the tubes i8 and seals them, and thereafter Hows over the upper edge of the delivery pipe 2l and into the milk pail.

l am aware that devices similar to what has been here described are used 'for the abstract-ion of milk from a cow but believje the use of a resilientvteat clamping member in conjunction with the hollow needle to he new, as also is the use of a. relatively small sie collecting vessel sealing with the first flow of milk theaccess of air to the teat.

What I therefore claim new and desire to be protected in by Letters Patent, is:

l. ln' a milking device, the combination with a flexible tube connected to each tcat ot' the animal, of a sealing vessel having a delivery tube to the milk pail projecting upwardv within it, a removable cover having a series of inlet tubes projecting through vit within the vessel to below the level ol the delivery outlet to each oi which inlet tubes a teat tube is connected.

2. A milking device, comprising the combination with av hollow needle closed at its upper end and pointed and apertured near the upper end below the point which needle is socketed into a tube, of a resilient clamp secured to the upper end of the tube which clamp is adapted to resiliently grip the lower part of the teat, and means for flexibly connecting each teat tube to the milk pail. I

A milking device, the combination with a series of` teat attachments, of a vessel having a delivery pipe which is connected to a milk pail said vesself having a removable cover in which a number of pipes are cured corresponding to the teat attachments said pipes projecting into the vessel below the level of the delivery pipe therefrom and means for flexibly connecting the teat attachments to the inlet pipes of the vessel. cover.

4. A milking device, comprising the combination with a tube for each teat olf the animal in the upper end of which tube a hollow apertured needle is removably inserted, a linger operated clamp secured to each teat tube which clamp is adapted to normally resiliently grip the lower part of the teal, a sealing vessel having a series of tubes inserted in the cover and projecting to near the bottom of t-he vessel and a delivery outlet from the bottom of the vessel the upper end of which outlet is above the level of the inlet tubes, means for 4flexibly connecting each teat tube to an inlet tube of the vessel, and means for lleXibly connecting the delivery outlet to the milk pail.

5. A milking device, comprising the combination with a teat tube, of a hollow needle removably inserted in the upper end of the teat tube and projecting upward therefrom, which needle is apertured in the upper end, opposed finger engaging levers pivotally connected to the teat tube the upper end of each lever having a crescent shaped portion adapted to grip the lower part of the teat, a sleeve slidably mounted on the teat tube below the fulcrum, a nut threaded on the teat tube below the sleeve, a coil spring between the nut and the sleeve and links pivotally connecting the sleeve to each clamp lever intermediate of the fulcrum and the finger engagement, and means for flexibly connecting the lower part of each teat tube to a sealing vessel which vessel delivers into the milk pail.

(3. A milking device, comprising the combination with a teat tube from the upper end of which a hollow apertured needle rojects, a linger operated clamp secure to each teat tube which clamp is adapted to resiliently grip the lower part of the teat, a spring simultaneously operating the clamp members to normally grip the teat, means lor llexibly connecting each teat tube to an inlet tube in the cover of a sealing vessel which inlet tube projects below the level of' the outlet tube, means for flexibly connecting the outlet tube to the milk pail, and a glass viewing tube between each teat connection and the pail.

In testimony whereof I allix my signature in presence of two witnesses.
